You don't have to dig very deep to strike their true motivations. Anybody that states that there is a scientific consensus that Humans are warming the Earth is nothing more than a Crack Pot to me. They are not responsive to facts, evidence or reason. They simply need to be utterly discredited and defeated intellectually and at the Ballet Box.
Sorry, but I happen to be a capitalist. I'm not left wing. I don't know what a "collectivist adjenda" is.
It is easy to understand that humans are adding heat to the earth. We burn coal, oil, natural gas, and the combustion creates heat. Hard to build a cold fire. And we can show how greenhouse gases like CO2 and methane insulate. Drive from city to country, and watch the temperature drop: our cities are warmer than the countryside. Even capitalists should be smart enough to see this.
But intelligence doesn't aid our intuition about what the climate is doing, or why it is doing it. Take any time scale, and we will find change. Choose one scale, and we'll see the earth cooling; choose another, and we'll see it warming. The time scale of our own memory doesn't get us very far -- even though we haven't had cold winters where I live in quite a while, that doesn't prove anything. That's where we need science, and good records.
The records are now pretty clear, the science better than ever. The earth's temperature does
fluctuate up and down. It was much warmer, with more atmospheric CO2, when coal was being formed. The poles were warm enough for plants to grow. It was much colder during the last ice age. The past two thousand years have been somewhat anomalous -- warmer than the planet normally is -- and we were on the way to cooling when the industrial revolution came along. Right now, all the records point to warming. See Wikipedia for samples: http://en.wikipedia.org/wiki/Temperature_record_of_the_past_1000_years
But your main point is that scientists don't agree that humans are causing the warming. You are wrong. Anyone who agrees with you on this is wrong. The headline findings of the fourth IPCC assessment were: "warming of the climate system is unequivocal", and "most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations." See http://en.wikipedia.org/wiki/IPCC_Fourth_Assessment_Report
and read the entire page. Wikipedia is written by everyone, not just anti-capitalists.
While it is easy to see that you are wrong, it is not so easy to see why you would have such an opinion. What is the benefit in believing that humans have had nothing to do with what is happening on this planet? I'm curious.
